Description

[Detailed description of the invention] [Industrial application field] This invention stirs piled up bulk materials such as compost in the vertical and horizontal directions for the purpose of supplying oxygen to the interior, and piles them up to a predetermined width and height. This invention relates to a switching device for making a switch.

[Conventional technology]

Compost needs to be stirred (turned) up and down and left and right from time to time for the purpose of accelerating ripening and drying by supplying oxygen, but conventionally, even if this was done mechanically, it was simply done by installing stirring blades on a running vehicle and driving the compost. While stirring, stirring was performed.

[The problem that the idea aims to solve]

However, according to the above-mentioned conventional technology, the compost placed on the ground is simply stirred by a stirring blade while the vehicle is running, so after stirring, the compost remains scattered, and it is necessary to pile it up in a pile. required manual or mechanical work.
For this reason, in the conventional technique, the work efficiency of turning back piles of loose materials such as compost is not good, so there was a problem that it was not suitable for large-scale piles.

Therefore, this invention was devised by focusing on the problems of the prior art described above, and it improves work efficiency by both turning loose materials and piling them up in one run of a vehicle. The purpose is to be able to handle large piles of loose items.

[Means to solve the problem]

The device for turning back piled-up bulk materials such as compost according to this invention forms a tunnel portion in the lower part of the vehicle in the front-rear direction in which the vehicle runs over the piled-up bulk materials such as compost, and also has a tunnel portion on the left and right sides of the front portion of the tunnel portion. A guide plate that opens toward the front is attached, a rotary blade is installed on the inner surface of the guide plate to gather loose materials toward the center in the width direction of the tunnel portion, and a stirrer is installed at the entrance of the tunnel portion to stir the loose materials. The agitator is provided with a lifting blade for moving loose material upward at a lower part of the entrance of the tunnel section.

[Effect]

When the device is advanced toward a pile of bulk materials such as compost, the bulk materials enter the tunnel portion of the device. At this time, the portion of the bulk material that is wider than the width of the tunnel portion is forcibly moved toward the entrance of the tunnel portion along the guide plate that is open toward the front and by the rotating blade. Therefore, loose objects located within the width between the tips of the left and right guide plates are moved to the entrance of the tunnel portion as the device travels.

Then, the loose material that has reached the entrance of the tunnel section is stirred by the agitator. Among the loose items that enter, the lower ones are lifted up. Therefore, the bulk material is stirred in the stirrer in multiple directions, including the vertical direction, and then fed into the tunnel section.

The tunnel part prevents the stirred bulk materials from scattering upward and in the left and right directions, and travels across the bulk materials while forming the bulk materials into a predetermined width and height as the device travels. remain at the rear. Therefore, after the device has traveled, the loose objects after turning are continuous with the width and height regulated by the tunnel.

The drawing shows an embodiment in which this invention is applied to a compost turning device, in which running wheels 2 are arranged on both left and right sides of the lower part of the vehicle body 1, and a tunnel that continues in the front and rear direction is provided in the center of the lower part of the vehicle body 1. Section 3 is formed.

Guide plates 4 that open forward in a V-shape are attached to the vehicle body 1 on the left and right sides of the front end of the tunnel section 3. On the inner surface of the guide plates 4, loose objects are placed in the width direction of the tunnel section 3. A rotary blade 5 is installed that moves toward the center. Rotating blade 5
A plurality of rotary disks 5a are rotatably supported by the guide plate 4, and a plurality of rotary disks 5a project radially from the center of rotation, and the loose objects are moved toward the tunnel portion 3 by rotation thereof.

The rear end of the guide plate 4 is connected to the vehicle body 1.
The guide plate 4 is directly supported by a vertical bar 6 fixed to the vehicle body 1 at its midpoint, and supported via a horizontal arm 7 whose front end is fixed to the guide plate 4. On the other hand, it can be raised and lowered by the support section. An actuator for raising and lowering is interposed between the vehicle body 1 side and the guide plate 4 side. An example of the actuator is a hydraulic cylinder 8, which will be described later.

Further, a stirrer 9 for stirring loose materials is provided at the entrance of the tunnel portion 3. This agitator 9 has two rotating parts between an upper plate 11 that forms part of the vehicle body and constitutes the ceiling of the tunnel part 3, and a lower plate 12 that is installed across the bottom of the tunnel part 3 from left to right. Bar 13
are vertically erected, and screws 14 constituting lifting blades are wound around both rotating rods 13 at the bottom.
A rod-shaped stirring blade 15 is provided protruding from the upper side thereof. Since the lower plate 12 bears the lower end of the rotating rod 13, it exists only at the lower end of the rotating rod 13 and has a small width in the front-rear direction.

Note that the screw 14 may be of any other shape as long as it forms a rising blade that moves the compost upward, and the stirring blade 15 may also be of any other shape as long as it has the function of stirring the compost. It may be hot.

A driver's cab 16 is provided on the vehicle body 1, from which the driver operates a plurality of operating levers 17 to operate the apparatus of the embodiment. Its operating system is as shown in Fig. 3, in which a hydraulic pump 19 is rotated by the rotation of the engine 18, which is a rotational drive source, and hydraulic pressure is supplied to various uses from an oil tank 21 that also serves as the vehicle body frame via a filter F. .

One of its uses is as a hydraulic motor 22 for rotating the running wheel 2, which is connected to the hydraulic pump 19 via a control valve 23, and one of its uses is as a hydraulic motor 24 for operating the agitator 9. , control valve 25
It is connected to the hydraulic pump 19 via a control valve 27, and one of its uses is a hydraulic motor 26 for rotating the rotary vane 5, and it is connected to the hydraulic pump 19 via a control valve 27. A hydraulic cylinder 8 that raises and lowers the guide plate 4 is connected to a hydraulic pump 19 via a control valve 28. Each control valve 23, 25, 27, 28 is individually controlled to open or close by one of the operating levers 17,
Further, return oil from each hydraulic motor 22, 24, 26 and hydraulic cylinder 8 is returned to the oil tank 21.

The turning device A thus configured moves forward toward the piled-up compost B, which is loose material, while stirring and turning the compost B, by operating the operating lever 17.

First, start from the end of the long pile of compost B.
When the device is moved forward in the longitudinal direction of the mountain, the compost B enters toward the tunnel section 3 of the device A. At this time, a portion of the compost B that is wider than the width of the tunnel section 3 is forcibly moved toward the entrance of the tunnel section 3 along the guide plate 4 that is open toward the front and by the rotating blades 5.

Therefore, the compost B located within the width between the tips of the left and right guide plates 4 is moved to the entrance of the tunnel portion 3 as the device A travels. Note that when the width of the piled compost B is less than or equal to the width of the tunnel section 3, it will be moved to the tunnel section 3 as it is.

Then, the compost B that has reached the entrance of the tunnel section 3 is stirred by the agitator 9, but at this time, since the agitator 9 is equipped with a screw 14 that moves the compost B upward at the entrance of the tunnel section 3, Among the compost B entering the tunnel section 3, the lower part of the compost B is lifted up. Therefore, the compost B is stirred up and down at the entrance of the tunnel portion 3, and is also stirred while being scraped backward by the stirring blades 15 above the screw 14. Therefore, the compost B in the agitator 9 is stirred in multiple directions including the vertical direction, and sufficient air is supplied between each compost before being fed into the tunnel portion 3.

The tunnel part 3 prevents the stirred compost B from scattering left and right and upward, and while traveling across this compost B, forms the compost B to a predetermined width and height so that the device A can travel. It will remain at the rear. Therefore, after the device A travels, the turned back compost B continues with the width and height regulated by the tunnel portion 3.

Guide plate 4 by actuation of hydraulic cylinder 8
Lifting and lowering shall be carried out in the following cases. That is, when turning over the compost B, the guide plate 4 is lowered and brought close to the ground. Further, when moving the device A to another position, the guide plate 4 is raised to avoid the guide plate 4 hitting a convex portion on the ground. Therefore, when the device A is used only in a place where there is no risk of the guide plate 4 hitting a convex portion on the ground, a configuration for raising and lowering the guide plate 4 is not necessary.

According to the embodiment, the two vertical rotating rods 13 of the stirrer 9 are rotated in the direction in which the stirring blades 15 move backward between the two rotating rods 13, and the stirring blades 15 are rotated to the left and right on the front side of the two rotating rods 13. The compost B on the outside is brought to the center and then splashed backwards, but the rotary rod 13 is installed horizontally in two stages, upper and lower, and near both ends there are screws that bring the compost B to the center of the tunnel section 3. At the same time, in the center of the rotating rod, a stirring blade is provided protruding from the center of the rotating rod, which rotates in the direction of bouncing up the compost B on the front side and scattering it backwards, and on the upper rotating rod, a stirring blade is installed protruding from the center of the rotating rod. It can also be configured to rotate in the same or opposite direction as the rotating rod. In this case, in the above embodiment, the rotating rod 1
3 becomes unnecessary.

Further, as the running wheels 2, it is also possible to employ known running means such as endless tracks instead of wheels as shown in the drawings. Furthermore, in the embodiment described above, the operating lever 17 is manually operated in the driver's cab 16, but each control valve 23, 25, 27, 2
It is also possible to remotely control 8 by wireless or wire. As a signal transmission means for such remote control, a known means shall be used.

Further, in the above embodiment, the apparatus is used for turning over compost B as bulk materials, but it can also be used as a device for drying granular materials (coke, grains, etc.) that are piled up in the open, for example.

[Effect of idea]

As explained above, according to this invention, work efficiency is improved by both turning back and stacking bulk materials in one run of the vehicle, and it is also possible to cut back and pile up large piles of bulk materials in this way. This can be done in a short time simply by running the invented device.
